A 1-month-old girl is found to have a right suprarenal mass on abdominal ultrasonography. The mass measures 4 cm in diameter. Imaging evaluation detects liver metastases. A skeletal survey is normal. Physical examination reveals multiple subcutaneous skin nodules. The mass is removed and confirmed to be a neuroblastoma. Analysis of the tumor reveals no N-MYC amplification. The next best step is:

A 1-year-old girl previously had a partial cystectomy for rhabdomyosarcoma of the bladder. After completion of vincristine, dactinomycin, and cyclophosphamide (VAC) chemotherapy, biopsy of the bladder reveals rhabdomyoblasts. Abdominal and chest computed tomography (CT) are negative. The next step is:
